In particular, this application claims priority to the U.S. Provisional Application 63/513,295, filed Jul. 12, 2023, which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of surgical methods and devices, and more particularly to arthroscopic ligament repair and/or reconstruction surgery.

BACKGROUND

Desired outcomes for arthroscopic ligament reconstruction or repair surgery are generally achieved by establishing the proper shape and placement of torn tissue. While performing such surgery, a surgeon typically makes a small incision in a patient's skin near the surgical site (e.g., a bone joint) to allow a drill assembly to be placed in the bone joint to create tunnels through the patient's bone, through which the surgeon can reconstruct or repair the torn tissue.

For a meniscal root repair, for example, one approach is to create a tunnel through the patient's tibia for the passing of a suture or wire. The suture is passed to the location of repair, and the meniscus is repaired with a button, anchor, or other suitable method of fixation. In some instances, the root repair may involve isolating the root and repositioning the root into a more suitable anatomical position. The current system of meniscus root guide requires pre-operative equipment to be sterilized and processed for the surgical procedure. Often, the MRI is unable to detect the meniscus root tear, leading to challenges with the meniscus root repair.

Accordingly, there is a need for devices and methods to help guide and properly align meniscal root repair procedures. There is a need for disposal guide to allow the meniscus root repair procedure to be perform during any surgical case without prior planning due to the nature of the tears and location of the tears.

Some examples of devices disclosed herein relate to a meniscal root repair guide configured to help align meniscal root repair procedures. Some examples disclosed herein relate to kits for use in meniscal root repair. Some examples disclosed herein relate to methods of guided meniscal root repair.

Meniscal Root Repair Guide

FIG. 1 illustrates a tibia 100, a tibial plateau 102, a medial meniscus 110, and a lateral meniscus 120. FIG. 2 illustrates a posterior root 112 of the medial meniscus 110 separated from the tibial plateau 102 by a distance illustrated in FIG. 2 by arrow 200, and consequently in need of repair. A plateau line 130 along an average plane of the tibial plateau 102 is shown in FIG. 1 . The plateau line 130 and the tibial plateau 102 as used herein will refer to a substantial average plane, or predominant plane, of the superior portion of the tibia 100 boney surfaces of the tibial plateau 102. Because the superior portion of the tibia 100 boney surfaces are irregular, such a substantial average plane, or predominant plane, is understood by those skilled in the art to serve as an angular reference for a tibia. The illustrated plateau line 130 is drawn along the tibial plateau 102 in a substantially anterior-posterior direction at an approximate medial-lateral midline of the tibia 100. The devices, systems, and methods herein can be used to drill to the medial meniscus root or the lateral meniscus root. The devices, systems, and methods herein can be used to drill to the anterior and/or posterior root.

Methods and devices described herein are illustrated in association with meniscal root repair; however, the methods and devices described herein may be equally applicable to other repairs. Reattachment or repair may be accomplished, for example and without limitation, on various parts of the medial meniscus 110, on various parts of the lateral meniscus 120, or any various other soft tissue structures. The soft tissue repaired or reattached may be, for example and without limitation, cartilage, ligaments, tendons, or any combination or part of these soft tissues or others. Bones to which soft tissue may be reattached include, for example and without limitation, a tibia, femur, patella, humerus, radius, or any combination or part of these bones or others. Soft tissue coupled, attached, reattached, repaired, or brought into contact with bone in various examples may consequently be given the opportunity to heal.

FIGS. 3A-3D illustrate various views of an embodiment of a meniscal root repair guide 300, also referred to herein as a repair guide 300. The repair guide 300 may include a guide handle 310, a drill guide 320, and a meniscal guide member 330. The meniscal guide member 330 may also be referred to as a reference member 330. The repair guide 300 may also include securement features 340 and 342, which may also be referred to as a drill guide securement feature 340 and a reference member securement feature 342.

The guide handle 310 may engage the drill guide 320. For example, a through hole in the guide handle 310 may allow engagement of the guide handle 310 and the drill guide 320. Securement feature 340 may be used to secure, connect, fasten, or otherwise couple the guide handle 310 and the drill guide 320.

The guide handle 310 may also engage the reference member 330. Securement feature 342 may be used to secure, connect, fasten, or otherwise couple the guide handle 310 and the reference member 330. In some examples, securement features 340 and 342 may be screws. For example, in some examples, securement features 340 and 342 may be knurled thumbscrews.

A repair guide 300 configured of individual, or modular, components may advantageously promote interchangeability, replaceability, and disposability of the components of the repair guide 300.

As depicted in FIG. 3D, the reference member 330 may include a first arm 332 and a second arm 334. The first arm 332 and the second arm 334 may define an angle 336. The angle 336 can be any desired angle to provide optimal anatomic fixation of the meniscus root.

The first arm 332 of the reference member 330 may be configured to engage the handle 310. In some examples, as depicted in FIG. 3C, the first arm 332 of the reference member 330 may engage a slot 312 of the handle 310. A securement feature 342 may be used to secure, connect, fasten, or otherwise couple the first arm 332 of the reference member 330 to the handle 310.

The second arm 334 of the reference member 330 may be configured to engage a patient's anatomical features. For example, the second arm 334 may be configured to engage the patient's tibia 100. The second arm 334 may be configured to engage the tibial plateau 102 of the patient's tibia 100. Engagement between the second arm 334 and the patient's tibia 100 may advantageously help to align subsequent meniscal root repair procedures, as more fully described below.

In some examples, the second arm 334 may include a guide assistance feature 338 at the tip of the second arm 334, as depicted in FIG. 3A. For example, the guide assistance feature 338 may include a fork feature, such as a forked tip at the tip of the second arm 334. The guide assistance feature 338 may be configured to engage an anatomical feature of the patient. For example, the guide assistance feature 338 may be sized and shaped such that it engages a portion of the patient's tibia 100. The guide assistance feature 338 having a forked feature may advantageously give the surgeon improved visual access while placing the meniscal root guide 300 and performing meniscal root repair procedures. For example, a forked feature at the tip of the second arm 334 may give the surgeon visual access from an intra articular camera view.

The reference member 330 may comprise a rigid material. The reference member 330 may be substantially flat, or thin, which may advantageously reduce the risk of injury or damage to a patient when the reference member 330 is inserted into the patient.

FIGS. 4A-4C illustrate an embodiment of a drill guide 320. In some examples, the drill guide 320 may comprise a screw. In certain examples, the drill guide 320 may include external threads. The drill guide 320 may include a proximal end 322, a distal end 324, and a length extending from the proximal end 322 to the distal end 324.

The drill guide 320 may include a channel 326. The channel 326 may extend through the drill guide 320. The channel 326 may extend from the drill guide proximal end 322 to the drill guide distal end 324. The drill guide channel 326 may be configured to allow passage of a drill pin, which may also be referred to as a guidewire, through the drill guide 320. For example, the channel 326 may be configured to allow passage of a drill pin through the drill guide 320, which may allow a surgeon to drill a tunnel into a patient's bone, such as a patient's tibia 100. The channel 326 may be configured to allow passage of a drill pin having an outer diameter of about 0.5 mm to 8 mm, 1 mm to 6 mm, 2 mm to 4 mm, 2 mm to 3 mm or about 2.5 mm such as about 2.4 mm. For example, the channel 326 may have a diameter that is slightly larger than the drill pin such as about 0.6 mm to 8.1 mm, about 1.1 mm to 6.1 mm, about 2.1 mm to 4.1 mm, about 2.2 mm to 3.1 mm, or about 2.5 mm or about 2.6 mm, or just slightly larger than about 2.4 mm. In certain examples, the channel 326 may be configured to allow passage of a drill pin having an outer diameter of about 2.4 mm to about 2.9 mm. For example, the channel may be configured to allow passage of a pin having an outer diameter of about 2.6 mm to about 2.7 mm. In such examples, the diameter of the channel 326 may be larger than the outer diameter of the drill pin.

FIGS. 5A-5C illustrate another embodiment of a meniscal root repair guide 500. The repair guide 500 may include a guide handle 510, a drill guide 520, and a meniscal guide member 530. The meniscal guide member 530 may also be referred to as a reference member 530. The repair guide 500 may also include a drill guide securement feature 540 and a reference member securement feature 542.

The drill guide securement feature 540 may also be referred to as a ratcheting component, a release slide, or a securement slide. When the drill guide securement feature 540 is in an open, or down, position, the drill guide 520 may be permitted to move freely or loosely in an axially direction within the guide handle 510. For example, when the drill guide securement feature 540 is in an open position, a surgeon may advance the drill guide 520 into a patient's tissue, as further discussed below. The drill guide securement feature 540 may use a spring 544 to secure the drill guide 520.

Positioning the drill guide securement feature 540 in a closed, or up, position may cause the drill guide 520 to be axially fixed relative to the guide handle 510. When the drill guide securement feature 540 is in the closed position, the drill guide 520 may not move axially relative to the guide handle.

In the closed position, the drill guide securement feature 540 may engage notches, grooves, detents, or other engagement features of the drill guide 520 in order to secure the drill guide 520 relative to the guide handle 510. In some examples, one side of the drill guide 520 may comprise notches, grooves, detents, or other engagement features, and the other side of the drill guide 520 may be substantially smooth. This may advantageously facilitate smooth insertion and removal of the drill guide 520 while also permitting engagement of the drill guide 520 with the drill guide securement feature 540. In certain examples, the drill guide 520 may comprise notches, grooves, detents, or other engagement features on all sides of the drill guide 520. In some examples, the drill guide 520 may comprise notches, grooves, detents, or other engagement features along the entire length of the drill guide 520. In certain examples, the drill guide 520 may comprise notches, grooves, detents, or other engagement features along a portion of the drill guide 520. A sliding drill guide securement feature 542 may advantageously allow a surgeon to quickly secure and/or release the drill guide 520 relative to the guide handle 510.

Method of Repairing a Meniscal Root

The above-described features of the meniscal

root repair guide

300, 500, 900 can help guide and properly align meniscal root repair procedures. An example method of repairing a meniscal root is described with further reference to FIGS. 1-6 .

A surgeon may make a small incision in the patient's skin near the surgical site. The site of the meniscus tear may then be visually evaluated using a probe or rasp. Cartilage may then be removed from the location of repair. After the site of the meniscus tear has been evaluated and prepared for repair, a meniscus root repair guide 300 may be used to help facilitate the meniscal root repair. In certain examples, the meniscal root repair guide 500 can be placed at the anatomic footprint of the root. The meniscal root repair guide 500 can be used to ensure the drill guide 520 will exit at the footprint of the meniscus root anatomy. In some examples, the drill guide 500 is the 2.4 mm drill guide or any other suitable drill guide such as those disclosed herein.

A meniscal repair guide 500 may be provided. The repair guide 500 may be in a first configuration, which may also be referred to as a retracted configuration. In the first configuration, the guide handle 510 may engage the reference member 530. A reference member securement feature 542 may provide for secure engagement of the handle 510 and the reference member 530. For example, reference member securement feature 542 may comprise a thumbscrew which may be operated to apply a compressive force to the reference member 530 and guide handle 510.

In the first configuration, a drill guide 520 may be in a retracted state. In its retracted state, the distal end 524 of the drill guide 520 may be positioned within the guide handle 510. In certain examples, in its retracted stated, the distal end 524 of the drill guide 520 may protrude just slightly from the guide handle 510. Alternatively, in the first configuration, the drill guide 320 may not yet engage the guide handle 510.

With the repair guide 500 in its first configuration, the reference member 530 may be inserted into the patient. For example, the second arm 534 of the reference member 530 may be inserted into the patient through an incision in the patient's skin. The reference member 530 may be positioned such that it engages an anatomical feature of the patient. For example, the reference member 530 may be positioned such that it engages the patient's tibia 100, or the tibial plateau 102 of the patient's tibia 100. The reference member 530 may be positioned such that the guide assistance feature 538 engages an anatomical feature of the patient, such as the patient's tibia.

With the reference member 530 positioned such that it engages an anatomical feature of the patient, the drill guide 520 may then be advanced distally to an extended state. In advancing the drill guide 520 to its extended state, the drill guide 520 may be inserted into the patient. For example, the drill guide 520 may be inserted into the patient through an incision in the patient's skin. In certain examples, the drill guide 320 may be advanced using a pushing motion, a screwing motion, or a combination of pushing and screwing motions.

With the drill guide 520 advanced to its extended state, a drill guide securement feature 540 may provide for secure engagement of the handle 510 and the drill guide 520. For example, drill guide securement feature 540 may comprise a ratcheting component, which may also be referred to as a release slide or a securement slide, configured to engage drill guide 520. Alternatively, as previously discussed, drill guide securement feature 540 may comprise a thumbscrew which may be operated to apply a compressive force to the drill guide 520 and handle 510.

With the drill guide 520 in its extended, or deployed, configuration, a drill pin 620 may then be advanced through the channel of the drill guide 520. In some examples, a drill pin 620 having an outer diameter of 2.4 mm or about 2.4 mm (such as described herein) may be advanced through the channel of the drill guide 520. In certain examples, the drill pin 620 may have an outer diameter of about 2.4 mm to about 2.9 mm (such as described herein). In some examples, the drill pin 620 may be operated to form a tunnel in the patient's tibia. Such a tunnel in the patient's tibia may allow for passage of suture, wire, or other method of fixation.

With the drill pin 620 inserted into the patient's tibia, the surgeon may remove the drill guide 520 and the reference member 530 from the patient. A cannulated drill bit 630 may then be advanced over the drill pin 620. With the cannulated drill bit 630 advanced to the site of repair, the drill pin 620 may then be removed from the patient.

In certain examples, the drill pin 620 and the cannulated drill bit 630 may be advanced simultaneously into the patient. The drill pin 620 may be positioned within the channel of the cannulated drill bit 630, such that the drill pin 620 and the cannulated drill bit 630 are concentric with each other when inserted into the patient. The drill pin 620 and the cannulated drill bit 630 may be advanced through the channel of the drill guide 520.

A surgeon may then pass suture, wire, or another method of fixation through the channel of the cannulated drill bit 630 and to repair the meniscus tear. A surgeon may pass the suture, wire, or other method of fixation via a delivery device 640. The meniscus may be repaired with a button, anchor, or other method of fixation.

FIG. 9A is a perspective view of another example of a meniscus repair guide 900. FIG. 9B is a side view of the example of the meniscus repair guide 900 of FIG. 9A. FIG. 9C is an exploded view of the example of the meniscus repair guide 900 of FIG. 9A. FIG. 9D is a zoomed in view of an engaged ratcheting mechanism of the example of the meniscus repair guide 900 of FIG. 9A. FIG. 9E is a zoomed in view of a disengaged ratcheting mechanism of the example of the meniscus repair guide 900 of FIG. 9A. FIG. 9F is a perspective view of the example of the meniscus repair guide 900 of FIG. 9A engaging a bone. FIG. 9G is a side view of the example of the meniscus repair guide 900 of FIG. 9A engaging a bone.

The meniscus guide 900 can be similar to the meniscus guides 300, 500 described herein. The meniscus guide 900 can include a knob 942 that allows the reference member 930, or guide member, to be adjusted along the handle 910. The reference member 930 can be moveable with respect to the handle 910. A dial, switch, or other component may be used to move the reference member 930.

The knob 942 can be rotated to adjust the position of the reference member 930 along the handle 910. The reference member 930 can include two arms forming an angle. The reference member 930 can include a first arm 935 that can fit within a cavity 915 of the handle 910. The reference member 930 can include a second arm 931 with an engagement component 938 at the distal end.

The knob 942 can include a shaft that extends through the central aperture 936 of the securement portion of the reference member 930. The shaft of the knob 942 can also extend through an aperture 911 in the handle 910. Rotating the knob 942 can adjust the first arm 935 up and down in the cavity 915. A user can adjust the reference member 930 using the knob 942 while the reference member 930 is positioned on a bone. This can adjust the angle of the drill guide 920 on the bone due to the change in position of the handle 910 relative to the reference member 930.

In some examples, the first arm 935 of the meniscus guide 900 can be visible while the user is adjusting the angle of the reference member 930. In some examples, the first arm 935 of the reference member 930 can be marked with degrees. This marking can indicate the angle between the reference member 930 and the drill guide 920 when the knob 942 is aligned with the marking. Advantageously, this can indicate to a user the angle at which they can drill into the anatomical feature.

The engagement component 938 can be used to contact an anatomical feature, for example a bone. Tools, for example sutures, that extend through the bone can be routed through the engagement component 938. The engagement component 938 of the reference member 930 can include two curved portions that extend laterally from the distal end of the guide member. The engagement component 938 can be wider than the rest of the reference member 930. The engagement component 938 can be U-shaped.

The meniscus repair guide 900 can include a drill bit 960 on the distal end of the drill guide 920. The drill bit 960 can be an elliptical drill bit. For example, the drill bit 960 can be circular or ovoid. The drill bit 960 can be malleted into the anatomical feature. Advantageously, the drill bit 960 can be sized and shaped to secure to the anatomical feature easily. For example, the circular drill bit 960 can be malleted into a tibial bone.

The drill guide 920 can include a drill guide knob 922 on the proximal end. The drill guide knob 922 can be rotated to extend and retract the drill guide 920. The drill guide knob 922 can be shaped for efficient and easy rotation by a user. The drill guide knob 922 can be cylindrical with an inwardly depressed mid-section. The diameter of the drill guide knob 922 can be smaller near the center along the longitudinal axis. A user can enact force on the drill guide knob 922 to mallet the drill bit 960 into the anatomical feature. Tools can be passed through the channel of the drill guide 920. For example, a suture can be passed through the drill guide 920 and extend into a cavity in the anatomical feature. The tools can be passed through a proximal end of the drill guide knob 922. The tools can pass through the center of the drill bit 960 along the longitudinal axis. Tools can extend through an aperture on the distal end of the drill bit 960. Once the drill guide 920 is in position, a pin, reamer, or drill bit may be used to form a tunnel in the anatomical feature, for example a patient's bone.

The meniscal repair guide 900 can include one or more sets of spring-loaded features for engaging the ratchet of the drill guide 920. The securement components can selectively lock the drill guide 920 in place relative to the handle 910. For example, the meniscal repair guide 900 can include two sets of spring-loaded features for engaging the ratchet of the drill guide 920. In some examples, the meniscal repair guide 900 can include between 3 and 10 sets of spring-loaded features for engaging the ratchet of the drill guide 920. The spring-loaded features 944 can include a ratchet, a spring, a cap, and/or a spring cup. The spring-loaded features 944 can engage grooves 924 of the drill guide 920 to secure the drill guide 920 in place. The grooves 924 of the drill guide 920 can extend longitudinally along the drill guide 920. The grooves 924 can be cut orthogonal to the centerline axis of the drill guide 920.

As shown with respect to FIGS. 9D and 9E, the drill guide 920 can be rotated to engage or disengage the grooves 924. The drill guide knob 922 can be used to rotate the drill guide 920. In some examples, the drill guide 920 can include a divot opposite the grooves 924 to receive part of a ball plunger 946.

In some examples, the meniscal repair guide 900 can include a ball plunger 946 for engaging the drill guide 920. The ball plunger 946 can engage the drill guide 920 when the ratchet mechanism is engaged. Advantageously, engaging the drill guide 920 with both the spring loaded features 944 and the ball plunger 946 can increase the stability of the drill guide 920.

The drill guide 1120 can include a drill guide knob 1122 on the proximal end. The drill guide knob 1122 can be rotated to extend and retract the drill guide 1120. The drill guide knob 1122 can be shaped for efficient and easy rotation by a user. The drill guide knob 1122 can be cylindrical with an inwardly depressed mid-section. The diameter of the drill guide knob 1122 can be smaller near the center along the longitudinal axis. A user can enact force on the drill guide knob 1122 to mallet the drill bit 1160 into the anatomical feature. Tools can be passed through the channel of the drill guide 1120. For example, a suture can be passed through the drill guide 1120 and extend into a cavity in the anatomical feature. The tools can be passed through a proximal end of the drill guide knob 1122. The tools can pass through the center of the drill bit 1160 along the longitudinal axis. Tools can extend through an aperture on the distal end of the drill bit 1160. Once the drill guide 1120 is in position, a pin, reamer, or drill bit may be used to form a tunnel in the anatomical feature, for example a patient's bone.

The meniscal repair guide 1100 can include one or more sets of spring-loaded features for engaging the ratchet of the drill guide 1120. The securement components can selectively lock the drill guide 1120 in place relative to the handle 1110. For example, the meniscal repair guide 1100 can include two sets of spring-loaded features for engaging the ratchet of the drill guide 1120. In some examples, the meniscal repair guide 1100 can include between 3 and 10 sets of spring-loaded features for engaging the ratchet of the drill guide 1120.
